WarningsThe following are general warnings related to the setup, use, grounding, maintenance and repair of this equipment. Additional, more specific warnings may be found throughout the body of this manual where applicable. Symbols appearing in the body of the manual refer to these general warnings. When these symbols appear through the man-ual, refer back to these pages for a description of the specific hazard.

Warnings

Fire and Explosion HazardImproper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and result in fire or explosion and serious injury.

• The system is for use with water-based materials only. Only use fluids compatible with the equip-ment. Refer to Technical Data of all equipment manuals. Read fluid and solvent manufacturers warn-ings.

• Ground all equipment in the work area. See Grounding and Electrical Requirements, page 6.

• If there is any static sparking or you feel an electric shock while using this equipment, stop spraying immediately. Do not use the equipment until you identify and correct the problem.

• Keep work area free of debris, including solvent, rags and gasoline.

• Comply with all applicable state and national fire, electrical and safety regulations.

• Keep a fire extinguisher in the work area.

Equipment Misuse HazardEquipment misuse can cause equipment to rupture, malfunction, or start unexpectedly and cause serious injury.

• Before operating this equipment, read all manuals, tags, and labels, including material labels and instructions.

• Do not expose system to rain. Always store system indoors.

• Do not alter or modify equipment.

• Do not spray cementitious materials.

• Do not exceed maximum working pressure of lowest rated component in your system.

• Check equipment daily. Repair or replace worn or damaged parts immediately.

• To reduce risk of serious injury, including electric shock and splashing fluid in eyes, follow Pressure Relief Procedure on page 6 before servicing the unit.

• Do not kink or over bend hoses or use hoses to pull equipment.

• Route hoses away from traffic areas, sharp edges, moving parts and hot surfaces. Do not expose Graco hoses to temperatures above 130° F (55° C) or below -35° F (-37° C).

• Air hoses at the compressor end, can get very hot! Allow sprayer to cool down 15 minutes before removing air hose.

• Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local, state and national guidelines.

• Never directly inhale compressed air. Compressed air may contain toxic vapors.

Warnings

311771E 3

Electric Shock HazardTo reduce the risk of electric shock:

• Be sure sprayer is adequately grounded through electrical outlet, page 6.

• Use only 3-wire, extension cords.

• Make sure ground prongs are intact on sprayer and extension cords.

• Do not operate with cover removed.

• Turn off sprayer. Follow Pressure Relief Procedure, page 6, and unplug unit, before removing any parts.

Pressurized Equipment HazardFluid from gun, leaks or ruptured components can splash in the eyes or on skin and cause serious injury.

• Follow Pressure Relief Procedure, page 6 when you stop spraying and before cleaning, checking or servicing.

• Do not point spray gun at anyone; put hand, fingers or rag over nozzle, or stop or deflect leaks with your hand, body, glove, or rag.

• Wear protective clothing, gloves, and eyewear.

Cleaning Solvent Hazard with Plastic PartsUse only compatible water-based solvents to clean plastic structural or pressure-containing parts. Many solvents can degrade plastic parts to the point where they could fail. Such failure could cause serious injury or property damage. See Technical Data on page 19 of this instruction manual and in all other equipment manuals. Read fluid and solvent manufacturer’s warnings.

Personal Protective Equipment You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic fumes, burns, and hearing loss. This equipment includes but is not limited to:• Protective eyewear • Clothing and respirator as recommended by the fluid and solvent manufacturer• Gloves• Hearing Protection

CAUTION

Water or material remaining in unit when temperatures are below freezing can damage motor and/or delay pump startup.

To insure water and material are completely drained out of unit:

1. Remove material line from sprayer.

2. Tip sprayer up as shown.

Before adding material or starting unit in cold weather, run warm water through pump.

Install burp guard (J) before adding material to hopper. When only a small amount of material remains in the hopper, the burp guard prevents material from shooting out when the sprayer is turned off. This material could splash into the operator’s eyes or skin.

Pressure Relief ProcedureTo reduce risk of injury, follow this procedure whenever you see this symbol throughout this manual, Also, perform this procedure whenever you:

• Stop spraying

• Check or repair any part of this system

• Install or clean spray nozzle

1. Turn Power Switch OFF.

2. Trigger gun into material hopper.

3. Disconnect air gun.

Grounding and Electrical RequirementsThis sprayer must be grounded. Grounding reduces the risk of electrical shock by providing an escape wire for the electrical current. The sprayer cord includes a grounding wire with an appropriate grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Check with a qualified electrician or if grounding instructions are not completely understood, or if in doubt as to whether the product is properly grounded. Do not modify plug provided; if it will not fit the outlet, have proper outlet installed by a qualified electrician.

120V AC Systems

• This equipment requires a 120V AC, 60 Hz, 15A circuit with a grounding receptacle. Do not use an adapter with this product.

Extension Cords

• Use only an extension cord with an undamaged, 3-prong plug.

• For 25 to 50 ft (7.6 to 15.2 m) cords, use 3-wire, 14

AWG (1.5 mm2) minimum.

• For up to 100 ft. (30.48 m) cord, use 3-wire, 12 AWG

(2.5 mm2) minimum.

Auxiliary Air Compressor (Required)

Minimum requirements 3.5 cfm @ 40 psi or 2.5 cfm @ 90 psi (see manual 311763 for detailed recommendations).

Generator Requirements (Alternate)

3500 W (3.5 KW) minimum.

Hose Size and Length

The system comes with a hose set consisting of a 3/4 in. ID x 20 ft (25 mm x 7.6 m) material hose.
